Application filled July 11,1921. Serial No. 438,?72.

To all whom it may concern:

Be it known that l, HENRY G. Gorns'rrun, a citizen of the United States, residing at @leveland,in the county of Cuyahoga and State of Ohio, have invented certain new and useful improvements in Fastening Devices, of which thefollowing is a specification. v V

My invention relates to improvements in fastening devices, and more particularly to improved means for connecting such fastening devices tothe cloth or mater al without the use of threads by sewing as 18 the common practice in attaching such fasteners.

My invention relates more particularly to that class or type of fastening devices com-' monly known as snap fasteners whereby the. head and socket members of such fas tenors may be readily attached to and clamped upon the adjacent cloth or material whereby such fastener members are more securely secured and may be more expeditiously applied than through the ordinary sewing operation by: fastening or connecting such. fasteners to the material parts to be connected. v

The primary object of the invention is to provide generally'improved means for attaching and securing fastening devices to the material such as cloth or the like, such fastening means being exceedingly simple in construction, cheap of manufacture, and eficient in use.

' With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated the cloth.

in some of its embodiments in the accom-' panying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure 1, is an enlarged central sectional view of a pair of snap fasteners embodying my improvements and attached to the adjacent members of the material or cloth to be connected.

Fig. 2, a view of the rear or under side of the socket member before being applied to Fig. 3, an edge view of the same. i

Fig. 4, an edge view of the head member.

Fig. 5, a view of the rear'or under side of the head member before being applied 4 and secured in position.

Fig. 6, a perspective view of a head member provided with a modified form of attachrngprongs.

rmilar numerals of reference designate like parts throughout all the figures of the drawings.

In the present instance ll have'shown my improvements applied to or incorporated in a fastening device of the usual snap firs: toner type.

As a means of applyin the socket and head members a and 6,to t e separate parts or members 2 and 3, ofthe cloth or material to be connected as shown in Fig. l, of the drawings, 1 provide the ,under sides of the socket and head members a and 6, with attachrng prongs 5 and 7, respectively, said prongs being preferably of substantially angular shape as shown and being pointed so that the same may be readily driven into the material to penetrate the latter.

The separate attaching prongs or tines are preferably formed near the outer periphery of the socket and head. members and normally extend in a plane substantially at vided with abeading 4, on its outer under.

side the edges of said beading terminating in the tapered cloth penetrating and attaching prongs 5 the under side of the beading 4: forming an annular shoulder or support to cooperate with the inwardly bent prongs 5, when the latter are upset and clamped downwardly as shown most clearly in Fig. 1, of thedrawings.

The socket/member a, is provided with a central head receiving opening 9, formedby means of the socket 9, and the latter is preferably provided with slots 9 in which the arm 1330f the spring member 13, are ,adapted to operate in engaging the shoulder 10 of the head 8, of the head member 6.

It will be seen that the beading i forms a shoulder 4 and that the socket head 9, forms a central support'relative to the inwardly Y extendin attaching prongs 5, as shown most clear y in Fig. 1, of the draweferr'in Fig. 6, of t e drawings, it will be seen that as distin ished from the form of prongs hereinbefore described, the attaching prongs 7 are struck out of the metal leaving into the modification shown in Bil Edd

' wardly'extending tapered openings 12, said adaptedto initially penecode and to be thereirection in the act of inga supporting shoulder on the face side of the material and extending approximately parallel therewith and said prongs edge desireto secure by Letand said attachin aneaaeoe being bent inwardly beneath the material in cooperative relation to said supporting shoulder.

2. In a fastening device, a disc-shaped fastener body terminating at its edges in an inwardly curled annular beading on its under side, said beading terminating at its in inwardl extending attaching prongs, the base 0 said beading forming a shoulder extendin substantially parallel with the face of t e fastener bodytn rest on the face side of'the subjacent material prongs being bent inwardly beneath said material in cooperative relation to said shoulder when attached.

In testimony whereof .I have aflixed my signature.
